Hi
I have got a similar problem (in version 3.4.1), I did install the oracle ojdbc driver (ojdbc6.jar) in preferences / Data management / Connectivity / Driver Definitions.
But in the configuration dialog of the Database Connector I cannot select oracle.jdbc.driver as database driver, it is missing from the dropdownlist.
When I create a SQL development project using the new project wizard, I can use this driver and I can connect to my DB.
How can I configure this driver for the Database Connector??
